problem capturing in high quality

[qwerty99]

when i capture something and the video is moving fast these horizontal lines appear on the screen. but thats only when the video is in high quality. if i campress it to vcd then it goes away. but i prefer to compress my videos to svcd so the lines still come. anyone know why this happens? i'm using virtualdub and huffyuv when i capture a video

What are you capturing? TV, VHS, camcorder video?

cable TV

After you make the SVCD, do the lines still appear on your TV? They shouldn't, as what you see is probably interlacing, and is part of TV video, just being picked up by your computer. Once you burn your SVCD and play the video on your TV, the lines should no longer be visible.

i don't burn the svcd and play them on my TV. i just play them on my computer and the lines come. it only goes away when i convert it to vcd not svcd. is there something i can do so it doesn't come up even in the huffyuv file?

Yea... When capturing video in VirtualDub just add a deinterlacing filer. I think the commands are 'video' 'filters' 'add' 'deinterlace' 'blend together' 'ok'. That should deinterlace your AVI captures.

Good luck.

i just tried it but the lines are still there. is there anything else i can do? add another filter or something?

If you added the deinterlace filter 'then' captured an AVI file with VirtualDub, you shouldn't have interlacing lines. Then maybe you're not seeing interlacing lines but something else.

Here is an example of interlace lines. Does this look like what you mean?

yeah its like that. but when i open the video those lines only come if i make it full screen. if i leave the video the size it is then they don't appear

That filter is for deinterlacing the video during capture. To deinterlace existing files you would load the filter and the video in VirtualDub and reprocess (reencode) that file which would then deinterlace it.

Your VCD MPEG1 files are not showing the interlacing lines because they are being deinterlaced when they were created. The rest of your files are going to be interlaced video unless you setup your capturing or encoding programs otherwise, like using a deinterlacing filter in VirtualDub.

If you're capturing in VD and adding the deinterlacing filter and you still have the lines I don't understand. You shouldn't be having them now. Maybe you didn't set the program up properly.(?)

Hope this helps

yeah i'm still getting it on the test captures that i did. i went to video then filters. then i clicked add then clicked deinterlace. for deinterlacing mode i picked blend fields together. then i tried to capture. here is a screen cap of the test i did. you can't really see the lines until you zoom in

@ qwerty99 LOL - -

you have to look at the other window to see your filtered changes !!

You may need to enlarge your window or you can switch your window's
view by:

* Options/Swap input/output panes.

the is a video that i captured with the filter. the Options/Swap input/output panes just lets me see one of the two windows in virtualdub. i'm not sure why that matters. the whole video was capped with the filter. i'm not editing a video by adding the filter. is the deinterlace filter the only thing that can fix this, cause its not doing much?

Here's a link to the the Smart Deinterlacer Filter. It's an add-on filter for VirtualDub. I've tried it a few times a few months ago and it did a good job. It may work better for you. http://neuron2.net/smart.html I think it's a little better than the default dub filter.

Hope this helps ya.
Good luck.

i tried that filter but those lines still appeared. i tried changing the options on the filter but still nothing. when i watch the video the lines don't appear until i make it full screen. anyone have any other ideas?
